Specification of Letters Patent.

Patented July 14, 1908.

Application filed July 23, 1907. Serial No. 385,223.

To all whom it may concern:

Be it known that I, IRVING EYER, a citizen of the United States, residing at Wilmington, Newcastle county, State of Delaware, have invented certain new and useful Improve ments in Stamping, Dating, or Numbering Machines; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in stamping, dating or numbering machines; and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanations of the structures shown in the accompanying drawings of what I new consider my preferred embodiment from among other arrangements within the spirit and scope of my invention.

My invention consists in certain novel features of construction and in combinations and arrangements of parts as more fully and particularly set forth and described hereinafter.

Referring to the accompanying drawings Figure 1,-is a side elevation of the stamp. Fig. 2, is an end view. Fig. 3, is a vertical cross section. Fig. 4, is a top plan view of the base plate detached from the frame. Fig. 5, is a detail elevation of one of the spacing rings or washers. Fig. 6, is an end view of the reciprocating yoke detached and par tially broken away and showing the disk carrier and disks, an end head being partially broken away. Fig. 7, is a detail sectional view showing the base plate in cross section and a portion of a disk in printing position. Fig. 8, is a detail sectional view through the disk carrier, showing a disk thereon in eleva tion. Fig. 9, is a sectional view of the yoke, detached, showing the disk carrier in elevation with several disks thereon and shown in section, one leg of the yoke being shown as in the act of being swung out to permit removal of the carrier and the disks therefrom. Fig. 10, is a detail cross sectional view corre sponding to Fig. 8, but illustrating a modified form of carrier. Fig. 11 is a detail perspective view of the carrier of Fig. 8, show ing one spacing ring thereon, and one spring impelled pin or pawl lifted from the longitudinal socket.

The main frame of the stamp as shown in the specific example illustrated, consists of the top cross portion 1, having a central vertical guideway or tubular portion 2, to receive the vertical reciprocating stem or handle of the yoke, the two vertical legs or side bars 3, and the base, bottom or face plate 4.

The side bars 3, are rigid with the ends of the cross portion 1, and are usually longitudinally channeled at their inner faces to form guide or slide ways. For instance, these side bars can be formed by lengths of channel bars.

The frame on one side is shown provided with parallel lateral brackets 5, projecting from and rigid with the side flanges of the side bars 3, to receive the inking attachment. The side flanges of the bars 3, are shown recessed adjacent to the brackets and at the lower ends of the side bars, to permit the free swing of the inking attachment during the operation thereof.

The reciprocating yoke comprises a cross bar or head 6, parallel vertical legs 7, secured to the ends thereof and depending therefrom, and a handle or stem 8, rigid with the cross head 6, and passing up and adapted to reciprocate through the tubular guide 2, and above the guide provided with a usually removable knob 9. The handle contains any suitable spring 10, adapted to yieldingly uphold the yoke in normal position. This spring is shown at its lower end bearing against cross pin 11, carried by tubular guide 2, and passing loosely through a longitudinal slot in the stem or handle. The cross head and legs of the yoke can be formed of channeled metal bars as shown with the upper ends of the legs fitted and secured within the ends of the cross head, and with the legs longitudinally channeled at their outer faces. The yoke legs fit longitudinally within the channels of the frame side bars and are .adapted to reciprocate vertically therein.

The type disk carrier is fixed to and extends between the yoke legs and forms the axis on which the type disks are mounted and can be individually rotated. The carrier can be formed with a cylindrical circumferential bearing surface 1.2, for the type disks, as shown in Fig. 10, or the disk bearing surfaces of the carrier can be formed by spaced flanges 13 as shown in Fig. 8, usually ar ranged say about ninety degrees apart.

' Fig. 8.

In the form shown by Fig. 8, the longitudinal flanges extend throughout the length of the carrier and their outer longitudinal edges are arranged in the circle of the inner edges of the type disks.

In both forms of disk carrier, the same is formed at the top with a longitudinal open top groove or socket 14, extending through out the length of the carrier and the bottom wall or floor of this longitudinal socket is formed with a series of spaced parallel sockets, de ressions or spring seats 140, each-arrange radially of the carrier and at its up* per end opening through the floor of the longitudinal socket.

A series of separate reciprocating parallel spring impelled pins or pawls 15, is arranged in the longitudinal socket 14, radially of the disk carrier, and each pawl is pressed outwardly by its own spring 16, arranged in one of the spring seats 140 and compressed between the end wall thereof and the inner end of its pawl to yieldingly press the outer beveled end of the pawl beyond the circle of the disk carrier. I preferably provide a separate pawl 15, for each disk and a separate spring for each pawl. The pawls are loosely arranged in the longitudinal socket 14, and are guided by the side walls thereof.

The type disks are confined on the carrier and the pawls are confined in the longitudinal socket, by end plates or flat heads 17, secured to and closing the ends of the carrier and of the longitudinal socket. The end heads 17 are of slightly greater diameter than the outer circle of the carrier and project beyond the same and a short distance outwardly beside the end type disks thereon. The end heads are interposed between the inner faces of the yoke legs and the ends of the disk carrier and the headsand carrier are shown relnovably secured to the yoke legs by machine screws 18 passed inwardly through the legs and heads and into the carrier, although any suitable means can be employed for this purpose.

Any suitable number of usually similarly formed and constructed type disks 19, can be arranged on the carrier between the end plates or heads. In the specific example illus trated, each disk is in the form of a fiat ring or annulus formed of any suitable material having the radially projecting spaced printing type or character closely arranged around the periphery thereof. The central opening of each disk is of a diameter to receive the disk carrier so that the disks will all be properly centered on said carrier, and whereby said disks can be independently turned or rotated on the carrier as a center.

In the specific example illustrated, the inner edge of each disk is formed with usually V-shaped notches or depressions 20, to receive the looking or holding end of one of said pawls projecting from the carrier. These notches 20, are in number equal to the number of type and are spaced to correspond to the printing type so that a type of the disk will always be resented at the rinting point when the paw is in a notch. ach disk can be provided with any suitable printing characters, such as the letters of the alphabet, the punctuation marks, and the numerals from one to naught, although I do'not so wish to limit my invention, whereby through manipulation of the various disks, any desired combination of letters and printing characters can be presented at the printing position to imprint the desired matter in a Suitable means can be provided to space or separate the disks. For instance, I show thln fiat spacing rings or liners 21, loosely mounted on the carrier and interposed be tween and separating the disks. I show each ring formed with a radial inwardly ex- I tending projection or tongue 22, loosely projecting into the longitudinal sockets of the carrier to hold the ring against rotation. These tongues serve the further purpose of properly guiding, separating and spaclng the spring impelled disk locking pins or pawls and confining each pawl to, a position included within the plane of its disk so as to always bear outwardly against the inner edge of its disk and snap from notch to notch as the disk is turned on the carrier to bring the desired character to the printing point.

The fiat horizontal face or base plate 4, is rigidly secured to the lower ends of the frame side bars by any suitable means. For instance, I show the ends of the plate formed With fiat vertical ears 40, engaging and removably secured to the flat outer vertical faces of said side bars by screws 41.

I provide one or both ends of the base plate with an outwardly projecting horizontal indicating pointer 42, which in the specific example illustrated, is formed by cutting a face to be imprinted is exposed, and through which slot the disk characters in the printing position project to'imprint said surface.

In the specific example illustrated, I show the base plate formed with two slots 44, on opposite sides of and parallel with and close to the central slot 43 to receive the disk printing characters immediately adjacent tothe characters in the printing position or line so that when the yoke is depressed to printing position, the characters in the printing position can project the required distance down through the slot 43 without causing adjacent disk printing characters to strike the top surface of the base, as said adjacent characters can move down into the recesses or depressions formed by said adjacent slots 44, see Fig. 7. To prevent said adjacent characters engaging the surface being imprinted, I show the bottom surface of the base plate provided with a facing 45, of very thin sheet metal or other suitable material bridging the side or adjacent slots 44, and bent or lapped up over the outerside edges of the base plate and the edges thereof forming the central or printing slot 43.

Each printing disk can be independently turned by hand to bring the desired character thereof to the printing point and the independent pawl or pin of said disk will lock or hold the same in the desired position, irrespective of the remaining disks and without being released or freed by turning any one or all of the remaining disks. If so desired a small flat blade (not shown) can be employed having a fiat or chisel like end to engage the disks between the teeth thereof, and turn or rotate the same.

In the specific example illustrated, I show an automatic inking attachment comprising an elongated horizontal open top metal pan or holder 24, removably containing the inking pad 25. The pan and pad are in length not less than the length of the row of type disks, and the pan is carried by two curved vertical arms 26, at their lower or outer ends rigidly secured to the ends of the pad holder, and at their upper portions connected by transverse or horizontal pivot pins 27, to the outer ends of the brackets 5. The upper portions of the arms are parallel with and arranged at the inner faces of the brackets 5, and are formed with inwardly and downwardly inclined extensions 28, arranged between the brackets 5 and the outer faces of the end plates or heads of the disk carrier. The extension 28, of each arm is formed with a downwardly and inwardly inclined elongated cam slot 29, at its upper end terminating in a straight horizontal portion 30, just in rear of the pivot 27. The end heads of the carrier are provided with rigid pins or studs 31, projecting outwardly through said slots.

The arrangement is such that when the yoke and printing devices carried thereby,

are in their normal raised positions, the studs 31, will lie in the horizontal lateral extensions 30, of the slots, and will thereby exert an upward pull on the upper lateral ends of the pad holder arms hence tending to raise the lower ends of said arms and forcing the ink ing p'ad upwardly against the row of type printing characters that are located. in the printing position.

When downward pressure is exerted on the yoke to move the same and the printing disks down to perform a printing stroke,the studs 31, will press down on the lower edges of the horizontal -slot extensions 30, and thereby depress the upper lateral ends of the pad ho'lder arms, swinging the lower ends of said arms outwardly to carry the pad to one side and out of the path of movement of the descending type disks. The arms thus swing outwardly until the slots 29, assume a vertical position, so that the studs 31, can move down the lengths thereof and thus hold the arms and pad in withdrawn position during the printing stroke. When the yoke makes its upward or return stroke, the studs pass up through the slots 29, and when the studs reach the lateral ends 30, of the slots, the pad holder arms are thereby swung to normal po sition with the pad engaging the type as hereinbefore described. If so desired one pad holder arm only, can be provided with the slotted upper extension.

The disk carrier is provided with concentric end lugs or trunnions 130, rigid therewith and removably projecting through the end heads and into the legs 7, of the yoke to maintain the carrier properly positioned and centered in the yoke. Hence in order to render the carrier readily removable from the yoke, or the type disks readily removable from the carrier for purposes. of assembling, repairing or replacing, I secure one or both of the legs 7, in the cross portion 6, of the yoke, to permit outward swing of said leg or legs when the screws 18, are removed, such a distance as to clear the trunnions 130 and permit removal of one or both end heads 17.

In Fig. 9, I show one leg 7, at its upper end mounted on transverse pivot 70, so that when the yoke is slipped from the frame and screws 18, are removed, said leg can be swung outwardly and upwardly so that the end head 17, can be removed and the disks 19, and rings 21, and the paWls can be slipped from and replaced on the carrier.

It is evident that various changes might be resorted to in the forms, constructions and arrangements of the parts described, and that parts might be omitted or elements add.- ed, without departing from the spirit and scope of my invention as defined by the claims, and hence I do not wish to limit myself to the exact structures shown.
